Abstract (en)
[origin: US5138944A] Adjustable ink keys are adjusted to move associated portions of a doctor blade relative to associated portions of an ink roll of a printing unit. Each portion of the doctor blade is moved into contact with the associated portion of the ink roll. Each portion of the doctor blade is then moved a predetermined amount away from the associated portion of the ink roll after the portion of the doctor blade has moved into contact with the portion of the ink roll. A measured value associated with the position of the associated ink key is stored in memory. The stored measured value is indicative of the position of the associated ink key after the portion of the doctor blade has moved the predetermined amount away from the portion of the ink roll. The stored measured value corresponds to the lithographic zero position of the ink key. The stored measured value of the ink key is modified each time the portion of the doctor blade moves into contact with the ink roll and then moves the predetermined amount away from the ink roll.
